This is probably a really weird question for most, and I apologise if this doesn’t fit this community, I couldn’t find a more applicable one. I’m trying to find a roleplay group. It’s very strange and niche, but I’m looking for people interested in roleplaying as anthropomorphic countries (CountryHumans). The platform would specifically be Stoat Chat. If anyone is interested, DM me for the invite link!
Birthright was a setting in Advanced Dungeons and Dragons (so second edition ish?) with rules for playing like countries more than adventurers. Well heads of state and the such with politicking. I never played, but my husband did.
It wasn’t the most well known setting and I don’t think it ever got any updates unlike other settings (like faerun or ebberon etc) but it fits your idea of playing as nation states with tweaking!
